The DS remake of Megaman Battle Network has a new trailer fresh from the Capcom booth at Tokyo Game Show this year. I'll let the trailer do most of the talking, but know that this is also a crossover seeming to involve time travel as Shooting Star Rockman is present in Lan's time period. Have a look- Clearly has some major differences here and there. Look for it this November 12th in Japan. Sometime next year likely in US.
